Heat stroke occurs when the body’s own ability to control its temperature does not work. It usually occurs when it is very hot outside and the humidity is high. To reduce the risk of heat stroke you should drink more when it is hot. Be aware if you are kissing less than usual, as this is a sign that you need to get more fluid in you.
The risk of getting heat stroke increases if you work very hard in hot weather, for example running a marathon.
Heat stroke can be life-threatening, especially for young children and older people. Small children usually have not started their ability to sweat and therefore become extra sensitive to heat. Older people often have other physical problems that make them more affected.
The body needs to get used to the heat gradually, and usually has adapted to about a week in warm climates.
If you have a stroke, your body temperature is above 40 degrees. Other symptoms are:
- Nausea and vomiting.
- Visual disturbances.
- Dizziness, irritation and confusion.
- Fast heart rate.
- Reddish, dry skin.
You need to get care as soon as possible if you have had a stroke. You must immediately come to a cool place and get help to cool down the body, for example with a wet towel.
At the hospital you may need to get nourishment and salts directly into the blood in the form of drip.
